简单介绍R语言networkD3一系列网图的使用

力导向图

简单力导向图

library(networkD3)
src = c(rep("A",4),rep("B",2),rep("C",2),"D")
target = c("B","C","D","J","E","F","G","H","I")
networkData = data.frame(src,target)
simpleNetwork(networkData)

复杂力导向图

data("MisLinks")
data("MisNodes")
forceNetwork(Links = MisLinks,
             Nodes = MisNodes,
             Source = "source",
             Target = "target",
             Value = "value",
             NodeID = "name",
             Group = "group",
             opacity = 0.8)

桑基图

URL = paste0("https://cdn.rawgit.com/christophergandrud/networkD3/",
             "master/JSONdata/energy.json")
Energy = jsonlite::fromJSON(URL)
sankeyNetwork(Links = Energy$links,
              Nodes = Energy$nodes,
              Source = "source",
              Target = "target",
              Value = "value",
              NodeID = "name",
              units = "TWh",
              fontSize = 12,
              nodeWidth = 30,
              height = 300,
              width = 500)

树状图

辐射

URL = paste0("https://cdn.rawgit.com/christophergandrud/networkD3/",
             "master/JSONdata/flare.json")
Flare = jsonlite::fromJSON(URL,simplifyDataFrame = FALSE)
Flare$children = Flare$children[1:3]
radialNetwork(List = Flare,fontSize = 10,opacity = 0.9)

对角

1	diagonalNetwork(List = Flare,fontSize = 10,opacity = 0.9,height = 500)

聚类

1 2	hc = hclust(dist(USArrests), "ave") dendroNetwork(hc,height = 500)
